HPLC Method for Analysis of Mixture of Nitroimidazole Antibiotics on Newcrom Type Columns
April 26, 2023
Separation type: Bridge Ion Separation Technology, or BIST™ by SIELC Technologies
HPLC Method for Analysis of Secnidazole, Tinidazole, Metronidazole on Newcrom AH and Newcrom R1 Column by SIELC Technologies
High Performance Liquid Chromatography (HPLC) Method for Analysis of Secnidazole, Tinidazole, Metronidazole
Tinidazole, metronidazole, and secnidazole are all nitroimidazole antibiotics used to treat bacterial and parasitic infections.
Metronidazole is the most commonly prescribed among the three and is used to treat a wide range of infections, including bacterial vaginosis, trichomoniasis, and certain types of anaerobic bacterial infections.
Tinidazole is similar to metronidazole in its mechanism of action and is used to treat similar infections, but it has a longer half-life and can be administered less frequently.
Secnidazole is a newer nitroimidazole antibiotic with a longer half-life than metronidazole, which allows for a shorter treatment duration. It is used to treat trichomoniasis and certain types of anaerobic bacterial infections.
It is important to note that these antibiotics can have side effects such as nausea, vomiting, and diarrhea, and should only be used as directed by a healthcare professional. Additionally, alcohol should be avoided while taking these medications as they can cause a severe reaction.

These 3 nitroimidazole antibiotics can be separated and analyzed on a Newcrom AH (mixed-mode) and Newcrom R1 (reverse-phase) columns using an isocratic analytical method with a simple mobile phase of water, Acetonitrile (MeCN, ACN), and phosphoric acid buffer. The analysis method can be UV detected at 270 nm with high resolution and peak symmetry.

HPLC Method for Analysis of Metronidazole on Newcrom R1 Column
February 28, 2018
Application Column
Newcrom R1
The Newcrom columns are a family of reverse-phase-based columns. Newcrom A, AH, B, and BH are all mixed-mode columns with either positive or negative ion-pairing groups attached to either short (25 Å) or long (100 Å) ligand chains. Newcrom R1 is a special reverse-phase column with low silanol activity.

HPLC Retention Control of Antibiotics (Metronidazole and Norfloxacine) in Toothpaste
May 27, 2015
Commercially available toothpaste has been known to include antibiotics. To demonstrate the retention control on the mixed-mode column Primesep 100, toothpaste was spiked with the antibiotics metronidazole and norfloxacin. In a 13 minute method, retention of the antibiotics was controlled by adjustment in ratio of organic in the mobile phase. This method demonstrates the flexibility of using mixed-mode columns such as Primesep 100.
| Column | Primesep 100, 4.6×150 mm, 5 µm, 100A |
| Mobile Phase | MeCN/H2O |
| Buffer | H2SO4 |
| Flow Rate | 1.0 ml/min |
| Detection | UV, 250 nm |
| Class of Compounds |
Drug, Antibiotics, Hydrophilic, Ionizable |
| Analyzing Compounds | Metronidazole, Norfloxacine |
Application Column
Primesep 100
The Primesep family of mixed-mode columns offers a wide variety of stationary phases, boasting unprecedented selectivity in the separation of a broad array of chemical compounds across multiple applications. Corresponding Primesep guard columns, available with all stationary phases, do not require holders. SIELC provides a method development service available to all customers.
